Given:
Trapezoid with bases 10 and 20, and height of the trapezoid is 6.
To find:
The area of the trapezoid.
Solution:
We know that the area of a trapezoid is:

Where, h is the height of the trapezoid and
are bases of the trapezoid.
Putting
in the above formula, we get



The area of the trapezoid is 90 sq units. Therefore, the correct option is A.
Answer:
The correct answer is option <em>B. AA</em>

Step-by-step explanation:
Given two triangle:
and
.
The dimensions given in
are:

We know that the sum of three angles in a triangle is equal to
.

The dimensions given in
are:

We know that the sum of three angles in a triangle is equal to
.

Now, if we compare the angles of the two triangles:

So, by AA postulate (i.e. Angle - Angle) postulate, the two triangles are similar.
by <em>AA theorem.</em>
<em>So, correct answer is option B. AA </em>

Answer:
Given data, first determine which is the independent variable, x, and which is the dependent variable, y. Enter the data pairs into the regression calculator. Substitute the value for one variable into the equation for the regression line produced by the calculator, and then predict the value of the other variable.
Step-by-step explanation:
- Enter data into the regression calculator.
- Determine the regression equation.
- Substitute the correct value for x or y into the equation.
- Simplify to find the value of the other variable.
